Support crews pulled Nyad from the water after deciding that the risks were too high in the open waters for the athlete.

"We pulled her out of the water," crew member Steve Munatones told "Good Morning America" in a phone interview on Tueday. "The dangers were so great that we couldn't risk anyone's life, including her own."

Members from Nyad's team told "GMA" that Nyad suffered severe sunburn, a strained muscle and could barely walk. The swimmer was reported to be taken to Oceanside Marina in Florida's Key West for medical attention for her injuries. Nyad's lips and tongue were also reported to have swollen greatly because of the ocean's salt water.

Nyad started her journey on Saturday, Aug. 18. Enstarz previously reported that Nyad suffering jellyfish stings on her first night, all over her lips, neck, hand and forehead. Jellyfish stings were also the reason for her to cut short her third attempt at the voyage last year.

Though she swam alone, Nyad had a team that updated her fans through Twitter and other social media outlets regarding her progress. Her Twitter page was constantly updated and on Aug. 20, it was posted, "Still strong!...This AM, weather is clear...Seas are calm and Diana is swimming strong. "
